Even with the Errata, its not a problem.That was Erata'd to be scene long so it cannot be used for uplift.
You boost the animal's Intelligence temporarily a la Flowers for Algernon, then make a Pact, and as a condition of the Pact raise the animal's Intelligence permanently by buying Attribute dots. No Faith is spent.

Assuming a candidate animal that has, post-evocation, the average Faith potential of 2 that most mortals have(many dogs are a lot more attached to their humans than that, but lets just use this)?Demon the Fallen Core p253 said:No rolls are needed to reshape the mortal's soul.The mortal's Faith rating is used as a "pool" of points for buying effects and gifts that benefit the thrall, according to the following guidelines:
• A point of Faith can be used to repair chronic injuries or impairments — allowing a paralyzed character to walk or giving sight to a blind thrall. If the mortal is missing lethal health levels as an effect of his condition, they are converted into bashing levels,which can then heal normally.
• A point of Faith can be converted into 10 freebie points (see Character Creation, p. 122). These points can be used to buy or improve traits such as Attributes,Abilities or Willpower. They cannot be used for improving Backgrounds.
• One point of Faith can be used to impart one of the demon's inherent powers, such as immunity to mind-control. The thrall permanently benefits from this power,rolling Willpower (difficulty 7) to activate its effects.
• One or more points of Faith can be used to give the mortal a limited evocation from the demon's lore.This gift costs one to five Faith points, depending on the level of the evocation in question (i.e., a three-dot evocation would cost the mortal three of her Faith points.) To perform the evocation, the thrall must make a Willpower roll (difficulty 8), with the number of successes determining the scope and effect of the evocation.
• One point of Faith bestows one of the enhancements of the demon's apocalyptic form on the thrall. To benefit from the enhancement, the thrall must make a Willpower roll(difficulty 6). Success allows the thrall to use the enhancement for a scene. The demon can bestow more than one enhancement, but he must spend a point of Faith on each.
• Up to half of the thrall's Faith potential can be used to make the mortal a source of offered Faith, if the Storyteller approves (see Offered Faith, p. 250).
Example: Rebecca has found a thrall, a local police detective named James Wong. Rebecca agrees to improve Wong's health and vitality in return for his service. Most mortals have a Faith potential of just two, but Wong is also a church deacon with a strong core of religious belief, so he has three points of Faith potential. After a short ritual designed to impress Wong, Rebecca concentrates, reaches out with her soul and uses Wong's belief to reshape his essence.
Adam, Rebecca's player, can spend the three points of Wong's Faith potential to modify the character. The first point is converted into 10 freebie points, and Adam uses them to improve Wong's Stamina and Dexterity by one dot each. The second dot is used to give Wong the Increased Size enhancement of Rebecca's apocalyptic form, which he can assume with a successful Willpower roll. With the final Faith point, Adam gives Wong Rebecca's immunity to mind-control, ensuring that her servant cannot be corrupted by her enemies.
Lash could reserve 1 point of Faith potential for herself to make the candidate animal a source of offered Faith(1 Faith point/day).
Then turn the second point into 10 Freebie Points, and spend them on buying Attribute dots (5 freebie points each) or Willpower dots (1 Freebie point each) for the animal before the scene ends and the evocation expires.
Thats Intelligence +2. Alternatively, Intelligence +1 and Willpower +5. Voila, sapience.
Thats something that appears to be entirely rules-compliant, and she can add additional Attributes/powers/features later if she so chooses as her command of the Lore of Flesh grows(assuming she doesnt already have Lore 5).
The only impediment here is whether the Storyteller thinks its kosher or not.
And thats up to you.
